Background: It is incredibly important to ensure proper medication adherence as well as inhalation technique to control asthma and (COPD) chronic obstructive pulmonary disease. Both are required to achieve a full treatment effectiveness. Providing services in these two areas is the role of community pharmacists.

Aim: This study aims to determine whether pharmacy interventions can result in improved inhalation technique and adherence to medication in asthma and COPD patients in relation to reduced hospitalizations and severe exacerbations.

Methods: A systematic literature search was performed in the database PubMed and was carried out in the fall of 2022. SBU gallery was used for relevance assessment and followed as a method (Appendix 1). Inclusion criteria for the studies were determined according to PICO.

Results: This review examined seven studies showing the positive improving impact of community pharmacists' on patients' adherence to inhaled medicine and inhalation technique for asthma and COPD patients. Some studies have demonstrated that this method of treatment can reduce hospitalizations and severe exacerbations, but few studies have been conducted in this area. In addition, research is needed to determine the ideal frequency for educating and rechecking inhaler techniques in order to prevent technique degradation in patients.

Conclusions: In this review, it was shown that community pharmacists can play an important role in managing asthma and COPD, particularly in educating patients about inhaler technique and making sure that their medication is taken as prescribed. Despite this, their role in this area is yet to be fully appreciated, requiring more research.
